Effect of temperature-photoperiod interaction on growth and winter bud development in Norway spruce (Picea Abies)
(Master thesis, 2020)Woody species growing in temperate and boreal regions, like Norway spruce (Picea abies) have to enter dormancy to survive winter and freezing temperatures, while simultaneously maximizing their growing period. Dormancy is ... -
Effect of using insects as a dogfood ingredient: A perspective on technology and nutrition on focus to Lumbriculus variegatus, Hermetia illucens and Tenebrio molitor- A literature review
(Master thesis, 2021)The use of insect as food and feed has been in existence for a very long time as it was used as an alternative protein source for food and feed production. The current food crises has caused researchers to find ways of ... -
The Effect of UV Radiation on Myzus persicae and the Biological Control Agent Aphidius colemani
(Master thesis, 2020)Greenhouse light technologies are advancing, giving new opportunities in pest management such as UV treatments against pathogenic fungi. Little is known about how these methods affect other relevant organisms in protected ... -
Effects of Blue Light on Assimilation, Growth, Morphology, and Water Usage in Cucumber Seedlings
(Master thesis, 2023)Blått lys (BL) kan påvirke plantevekst og -utvikling på flere måter, og agurk (Cucumis sativus) er spesielt sensitiv for lyskvalitet. Formålet med denne studien var å undersøke hvordan ulike andeler BL påvirker assimilasjon, ... -
Effects of Candida utilis as a protein source and replacement of soybean meal and yeast with barley on feed utilization and nitrogen use efficiency in dairy cow diets
(Master thesis, 2020)An increasing global population requires increasing sustainable food production. Today, protein from soybeans is used in concentrates to dairy cows. Climatic conditions make it difficult to grow soybeans and other protein ... -
Effects of changes in the breeding goal on genetic improvement for maternal traits in Landrace pigs
(Master thesis, 2018)Maternal ability is becoming increasingly more important in today’s breeding practices, as it increases the animal welfare, as well as, decreases the economic cost related to the loss of animals. Because of the complexity ... -
Effects of concentrate supplementation on reproduction and lactation performance of F1-Small East African x Norwegian does
(Master thesis, 2011-04-14)Forty-five (12-15) months-old, grazing Small East African (SEA) x Norwegian (N) does (20.7 ± 0.6 kg BW) were used to determine effects of three dietary levels on reproductive and lactation performance for 17 months experiment ... -
Effects of culture conditions on the photoautotrophic growth and biochemical composition of Chlamydomonas reinhardtii, as a potential source for hydrogen production
(PhD Thesis;2014:85, Doctoral thesis, 2014)Hydrogen is a particularly attractive energy carrier, since its combustion produces water vapor only. The green microalga Chlamydomonas reinhardtii is able to produce hydrogen under sulfur-deficient anaerobic conditions ... -
Effects of day and night temperature and lighting conditions on growth, nutritional status and tipburn of lettuce (Lactuca Sativa L.`Frillice´) cultivated in controlled environment
(Master thesis, 2022)Growth chamber experiments were conducted with Lactuca sativa crisphead lettuce:`Frillice´ growing in nutrient film technique (NFT). The main objective was to study energy-efficient cultivation strategies without reductions ... -
Effects of daylight and high light periods on growth and quality of the green microalga Chlamydomonas reinhardtii
(Master thesis, 2014-08-12)The effect of high light intensities in form of daylight and simulated daylight conditions on the growth and quality of the green microalga Chlamydomonas reinhardtii was investigated. In the daylight experiments, cultures ... -
Effects of diet structure and feed availability on passage rate and nutrients digestibility
(Master thesis, 2014-08-12)The purpose of the experiment was to test the following hypotheses: birds have tendency for over-consumption of feed, and the extent of over-consumption varies through the day after a starvation period. Further, the ... -
Effects of dietary oxidation status and vitamin E level on performance, fillet quality and robustness to acute stress in Atlantic salmon (Salmo salar L.)
(Master thesis, 2012-05-18)The effects of oxidized dietary lipid and the role of vitamin E on the growth performance, biometric traits, blood parameters, muscle pH and fillet quality of Atlantic salmon (Salmo salar L.) were evaluated after a 79-day ... -
Effects of different cage environments on social behaviour and some behavioural welfare indicators in adult pair housed silver fox vixens (Vulpes vulpes) in autumn
(Master thesis, 2010-11-16)In recent years there has been an increasing concern for the welfare of animals in the fur production, especially regarding the housing conditions. The aim of this study was to examine the effect of two different housing ... -
Effects of different light intensities, light spectra and temperatures on the growth and fatty acid composition of the microalgae Acutodesmus obliquus
(Master thesis, 2019)The subject of this thesis were the effects of cultivation of different light intensities, spectral light areas and temperatures on growth and fatty acid composition in the microalgae Acutodesmus obliquus. While previous ... -
Effects of environmental enrichment on social cohesion, aggressive behavior and telencephalon cell proliferation in Atlantic salmon parr
(Master thesis, 2023)Much is known about the life cycle and growth of the Atlantic salmon, but there has been less focus on the behaviour and neurobiology of these animals in captivity and how they interact with each other and their environment. ... -
